Final answer:
Coal originates from the remains of ancient plants that were buried and compressed over millions of years to form a fossil fuel known as coal.
Explanation:
Coal is a fossil fuel that formed from the remains of ancient plants that grew in swampy environments millions of years ago. The process of coal formation, known as coalification, involves dead plants being buried in oxygen-poor conditions, preventing decay. Over time, the buried plant material undergoes heat and pressure, transforming into coal.
